The Department of Energy and other federal agencies have made significant investments in software performance engineering tools, which can be complex and difficult to use. Novice users first encountering a tools complexity and vast array of features are intimidated and easily frustrated. There is also a lack of advanced problem identification capabilities so users rely heavily on their o ...

The need for ever more sensitive, compact, rugged, and inexpensive optical sensors is particularly acute in the fields of homeland security, biological sciences, nuclear medicine, and nuclear and highenergy physics. The ability to detect the spatial location and time of arrival of single photons with increased accuracy represents the ultimate goal in optical detection for many of these application ...

The Arctic sea ice cover plays a major role in governing the exchange of energy between the ocean and atmosphere in the Polar Regions. As such, observations of ice extent and thickness, including temporal growth and melt cycles, improves our understanding of the ongoing global climate changes, and enhances our ability to predict future changes. Despite continual improvements in global climate mode ...

ABSTRACT: A fast, 1-cm diameter cylindrical gradient index (GRIN) nonlinear optical (NLO) refractive index lens, with large radial linear and nonlinear optical index gradients in all three optical axes will be fabricated using ink jet printing (IJP). The goal is to demonstrate the ability to modulate the third-order susceptibility by 1000x over silica. To achieve the desired performance, existin ...

ABSTRACT: Using roll-to-roll (R2R) -compatible inkjet-print (IJP) deposition and nanoimprint (NI) photolithographic patterning methods, a series of passive and electro-optic (EO) -modulated waveguide structures will be fabricated and characterized. The measured data will be compared to modeled results and the information will be used to improve device designs. Modeling will also be used to demons ...

ABSTRACT: High-yielding inkjet print (IJP) deposition technologies will be developed for hybridizing the ultra-small pitch semiconductor detector arrays and readout integrated circuits (ROIC). The goal is to develop a method, alternative to the thermocompression hybridization methods currently used, that can be used to hybridize high pixel density focal plane arrays (FPAs), with 5 micron, and sma ...

A multi-band dual-aperture SATCOM antenna is proposed to support rotary-wing aircraft thru-rotor performance at X, Ku and Ka-bands including Ku-band TCDL as an option. Our proposed effort focuses on a low-cost design with reduced height and leverages existing aperture and radome technology from our prime contractor partner Lockheed-Martin. It also leverages existing digital modem technology develo ...

BTech proposes the design and development of low-profile, innovative acoustic velocity sensors for measuring acoustic motion of sound waves in marine applications. Methods include increasing voltage sensitivity by novel connections, considerations of co-located preamplifiers, multiple plates, improved materials and more. An improved acoustic motion accelerometer sensor for hull arrays is proposed ...

ABSTRACT: Lightfield 3D displays are being developed to reduce viewer eyestrain normally found on stereoscopic displays caused by the mismatch of the focus and stereo vergence on the display. These lightfield or Field of Light Displays (FoLD) systems generate a light field by any of several approaches including holographic, volumetric, integral-imaging, and multiple-2D-depth-planes. The differen ...

This is a Phase II project to develop and evaluate the effectiveness of a responsively designed web application, Goal Guide, that enables individuals with intellectual disabilities and autism to effectively manage self-defined goals for everyday living across personal, educational, and vocational life domains. Users will be able to easily enter goals, work with data for each goal, engage with info ...
